Claims. (01. -156) This invention relates generally to the producthe space so formed. The mold member 6 is then tion of heat resisting panels, but is particularly raised and fastened in a higher position and the designed to be used in the making of doors for operation repeated until the whole length of the a common type of modern coke ovens which have casing is lined.

5 long, narrow, deep retorts which must be opened According to my present invention a sheet of 5 up completely at each end to permit the coke to metal lath 4, wire cloth, or other material adaptbe discharged in a mass by the action of a horied to form a reticulated septum is firstinserted zontally moving ram. Such doors are long, narin the casing 1, and the pocket thereby formed row panels usually formed of an outer metal filled with coal cinders, or other cheap, granular l0 casing with an inner facing and filling of reor loose material 5, which is non-combustible fractory cement or composition of refractories and will not carbonize or otherwise be seriously which has been allowed to set in said casing. The affected by high temperature, but will contain heat in the retort is so intense that a cement or a multiplicity of air cells so as to form an emother refractory composition of great heat recient heat insulating mass.

Part of this ness must be built up to protect the metal casing passes through the metal lath 4 and partway or frame of the door from the destructive action penetrates the cinder mass, thus keying the parts of high temperatures, and to reduce the loss of together to a sufficient extent.
